Vitreous humor tamponade product comprises solid particulate gas-generating reactants encapsulated in a biocompatible material with retarded solubility in aqueous media

摘要

Vitreous humor tamponade product for injection into the posterior chamber of a non-vitrectomized eye to generate a gas for displacing water from the posterior chamber comprises solid particulate reactants encapsulated in a biocompatible material with retarded solubility in aqueous media. The reactants generate an inert gas by reaction with aqueous fluid in the eye.
